PT fun times
Some background
In the Kraft pulping cycle, the most important process would arguably be the regeneration of the white liquor that is used to cook chips/sawdust. White liq. --> Black liq. --> Green liq. --> White Liq.
The black liquor is burnt in the recovery boiler to form an inorganic smelt that is dissolved in water to form green liquor. However, the smelt has to be properly dispersed otherwise there will be water/smelt explosions.
I was in the lab today and someone told me there was a problem with the dissolving tank. Then for the next minute or so, the building was audibly shaking and we were ready to evacuate. In a worst case scenario, the parking lot might have taken a good beating from the explosion (or was that the chip pile?.....I forget now). Anyhow, aside from the huge cost required to repair and fix this problem and weekend overtime for maintenance, it's business as usual. (On top of the fire that could've potentially destroyed our chip intake system a couple weeks ago).
